How Does WordPress Generate Feeds?

So how does WordPress generate the feeds for your blog?

By default WordPress gives you some settings related to syndication. Here’s a screenshot of these settings:

feed options

The first option sets how many feed items your feeds page should show. Pretty straightforward stuff.

The next radio buttons let you decide whether your feed should show a summary of your post or the full content.

When you enable only the summary, WordPress will only populate the <description> tag in the resulting RSS XML file.

When you enable the full text option, WordPress will populate the <description> and the <content> tags in the RSS output.

You’re probably asking how WordPress generates the text for the <description> tag. Good question. First it checks whether you have created any manual excerpts and uses those. If no manual excerpts are found, it will use the get_the_excerpt() function which in turn uses the wp_trim_excerpt() function to return a summary of 55 words. If the string is less than 55 words, then the content will be returned as is.
